Found in Valle de Cauca department of Colombia without locational data as a small sized, caespitose epiphyte with slender, erect, round in cross-section ramicauls enveloped basally by a close, tubular sheath above the base and another at the base and carrying a single, apical, erect, coriaceous, sessile, ovate, acute, braodly cuneate below into the petiolate base leaf that blooms in the spring on a fascile of solitary, .6" [1.5 cm] long, successive flowered inflorescence arising through a prostrate spathe from the base of the leaf.

Closely allied with P rowleei but distinguished by the inflorescence that is single flowered instead of racemose. The flowers are alos very similar butP quaternaria are distinguished by the slightly larger, multiveined petals that rae about as long as the sepals." Luer 1998
